Abstract
A two dimensional array of resistive bolometers (B) is arranged in rows and columns. Amplifiers (A0, A1 etc) amplify signals obtained from the bolometers. Instead of providing one amplifier per column, a smaller number of amplifiers is used each of which is connected to a plurality of column sense lines (L) via a multiplexer (M0, M1 etc).
